3-1...Configuration
The HEX is composed of the key components as the following : Chassis , Heat exchange Core , Controller Internal/External fan tray & dust filter .
3-2...Thermal path and airflow baffle
With forced convection using the axial fan , warmer return air will be blowing into the HEX ,the cooler supply air will be used to cool down the system ; On the opposite side , cooler air will be drawn into the lower inlet and push the heat out from the upper outlet .
The thermal exchange path is shown in the figure below.

Criterion: Monthly
1.Please kindly slide dust filter out upward from trail on external side
2.Use brush and low pressure air to blow out the dust or use water for cleaning
3.Slide dust filter into the rail back
3-4...Heat exchanger maintenance
Criterion: Quarterly
1.Please kindly slide out the dust filter first
2.Use screw driver to remove screw of both external / internal fan tray , be sure to disconnect the fan first , then take out the fan tray
3.Use brush and low pressure air to remove dust on both internal/external fan tray
4.Use brush and low pressure air to remove dust on HEX case and
